RU2554330C1 - Device for protection of neck and head - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention covers the device for protection of neck and head at collision of vehicle overturning. Proposed device is composed of belt 1 connected by its ends to two sides of car rear seat headrest 2 and crosswise belts 4. Device main belt is set at either the passenger forehead height by adjustment of headrest height. Device inner surface is provided with damping elements. Said device is used with standard safety belt. Unlike safety bags this device rules out the constraints related with smoking, use of cardio accelerator, glasses.

Description

The invention relates to the field of ensuring passive safety of vehicles, namely to individual means of protection, and can be used in their manufacture.

The most common individual means of passive safety in vehicles is the seat belt. By fixing the passenger’s position, he prevents injuries or reduces their severity by eliminating the dangerous movement of a person in a collision or sudden braking of the car, and also ensures its location, which guarantees the safe deployment of airbags.

However, practice shows that the seat belt is not sufficient protection: in a collision, it holds the person’s torso, but the head continues to move forward by inertia, sharply bending the neck, which can damage the cervical spine. Therefore, in addition to seat belts, the HANS head and neck support system or airbags are used. The HANS system requires the use of a protective helmet, so it is not widespread in road cars, and the expensive airbag system is used only once, after which it requires a complete replacement. In addition, the use of pillows imposes a number of limitations: pacemaker, glasses, smoking, the need to find a person at a certain distance in a certain position, without raising their hands. There is no data on how the airbag will work if a person instinctively closes his hands from impending danger. The condition for the operation of the pillows is that the impact force exceeds a predetermined value with a sharp deceleration of the car, which does not protect people in a standing car if another vehicle hits it.

Depending on the location, frontal, side, head, and knee airbags are distinguished, each of which is triggered by a certain type of impact. In premium cars, six to eight airbags can be installed separately for each type of accident, but in mass-market road cars, there are usually only two front ones designed to protect the driver and front passenger. There is no pillow for rear seat passengers, so there is a need for inexpensive head and neck protection devices for rear seat passengers.

The aim of the invention is to increase the safety of the passenger of the rear seat of the road car due to the inexpensive restraining means of protection of the head and neck, stopping the sharp movement of the head in any type of collision or capsizing of the vehicle.

The essence of the claimed technical solution is illustrated by a description of an example of its preferred implementation in combination with the accompanying drawings. The same item numbers are used throughout the description and in all drawings to refer to the same components and parts. In FIG. 1 shows a representative device, side view, in FIG. 2 - the same, top view.

The invention proposes a protection device made in the form of a belt 1 for the head 3, attached to the ends of the two sides of the headrest 2 of the rear seat of the car. Because in case of significant vertical movements, for example, when a wheel hits a pothole, as well as when the car overturns, the specified belt can get on the neck, as a result of which the user may be strangled, there are transverse belts 4, which will also protect the passenger from hitting his head against the inner surface of the roof in the situations mentioned. The inner surface of the device is equipped with damping elements.

The specified tool is used in conjunction with a standard seat belt and performs its functions, but for the head. The material for the manufacture of the device can be a lightweight durable material, such as plastic or carbon fiber, it is possible to use elastic tensile materials based on rubber, which have a shock-absorbing effect. In a preferred embodiment, the device is made of woven tape used for standard seat belts. The main belt of the device should be located at the height of the forehead of the passenger. The height of the protection device is adjusted separately for each passenger seat by adjusting the height of the head restraint. The device in normal conditions is located above and around the head, without touching it, without affecting the person until the moment of the accident, without restricting his movements, without creating a feeling of discomfort. At the same time, the main function of the headrest ensuring passenger safety is not violated.

Most road vehicles do not have side airbags. The specified holding belt protects the passenger not only from a frontal impact, but also from a side impact, as well as from a car directed at any angle to the direction of movement of the car, it will not allow heads of passengers sitting next to them in the rear seat to collide. A similar device can be used in child seats, especially if they have the ability to adjust the height of the head restraint, for example, as presented in patents JP 2000296734 A from 10.24.2000; RU 2334631 C2 dated 09.27.2008. For children, head and neck protection is especially important because the specific gravity of the child’s head is significantly higher than that of an adult.

It becomes possible to use the device on existing vehicles that do not have head and neck protection. To do this, it is enough to replace the head restraints with those equipped with the specified device.

The proposed device is a simple and effective means of reducing the severity of the consequences of accidents, an effective means of protecting the head and neck in all types of traffic accidents - frontal, side impact and rollover; restrictions on smoking, the use of a pacemaker, and glasses put forward when using airbags are removed.

The essence of the invention lies in the fact that the proposed low-cost restraint means of protection of the head and neck, stopping a sharp movement of the head in any type of collision or tipping of the car, which is a belt for the head, attached to the ends of the two sides of the headrest of the car seat. To eliminate the possibility of the specified belt shifting onto the passenger’s neck, as well as to protect it from hitting its head against the inner surface of the roof in case of significant vertical movements, for example, when a wheel hits a pothole, as well as when the car capsize, transverse belts are provided. The inner surface of the device is equipped with damping elements. The specified device is used in conjunction with a standard seat belt and performs its functions, but for the head.

The closest in technical essence to the invention are the solutions set forth in patents WO 2008127729 A1 of 10.23.2008; US 2009144886 A1 of June 11, 2009; WO 2009133524 A1 of 11/05/2009, which describes the designs of head-holding devices.

The technical result of the invention is to increase the safety of the passenger of the rear seat of the road car due to the simple inexpensive restraining means for protecting the head and neck, stopping the sharp movement of the head in any type of collision or rollover.

The specified technical result is achieved due to the fact that the proposed protection device, which is a belt for the head, attached to the ends of the two sides of the headrest of the car seat. To eliminate the possibility of the specified belt shifting onto the passenger’s neck, as well as to protect it from hitting its head against the inner surface of the roof in case of significant vertical movements, for example, when a wheel hits a pothole, as well as when the car capsize, transverse belts are provided. The inner surface of the device is equipped with damping elements. The specified device is used in conjunction with a standard seat belt and performs its functions, but for the head.
